Application led July 31, 1914. Serial No. 854,219.'

T all whom itmag/ concern Be it known that I, WILLIAM W. MAJOR, a citizen, of the United States, residing at Midlothian, in the `county of Ellis and State of Texas, have invented certain new and useful Improvements in Tire-Patches for Inner Tubes, of which the following is a specification.

My invention relates to patches for thealso close punctures in the inner tube, and

Iis used as an emergency device. Another object is to provide means for holding the patch in place without mutilating the inner tube or the outer casing or shoe and to provide flexible means for securing the patch on the inner tube and for hingedly connecting the meeting portions of the patch together so that the patch will hold the inner tube safe in the outer casing. @ther objects'and advantages will be fully explained in the following description and the invention will be more .particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application. f

Figure 1 illustrates a portion of an inner tube of a pneumatic tire, showing the inner face or circle with a patch applied thereto. Fig. 2 is a cross-section, taken on the line :1sof Fig. l' and showing the tire applied to a wheel rim. Fig. 3 is a broken longitudinal section of an inner tube with a part of a patch, showing the contraction of the inner tube when a patch is used onA the inner tube.

Similar characters of reference are used to indicate the same parts throughout the Several views.

Aiortion of an inner tube 1 is shown provide with a patch 2. Fig. 2 shows the inner tube 1 and the'patch 2 inclosed in a tire casing or shoe 3 which is applied toa wheel rim` The edges 5 and 6` of the patch lap past each other andthe edge 5 terminates in a feather edge, as shown 2. The patch 2 being constructed of elastic material and the longitudinal edges lapping in Fig.

past each other, the. patch will make a perfect seal. The end edges 7 oftheV patch also terminate with feather edges so that there will be no abrupt bending 'of the inner tube and the natural contraction of the tube will be gradual. The patch 2 is secured on the inner tube by a hinge connection. Strips 8 and 9 of soft and flexible leather are doubled and attached to the patch 2 by stitching, as shown in the drawings, or otherwise suitably attached to the patch. The meeting edges of the leather hinge are 'cut away alternately to form bearings and 11 for a pintle 12. The bearings 10,and 1l are thus interlocked and the bearings are formed by the doubling of the leather strips 8 and 9 and the pintle 12 is run through the interlocked portions or bearings 10 and 11. The strips 8 and 9 thus become the jaws of a hinge Vand the pintle 12 1completes the hinge so that the edges of the patch are hingedly connected. One end of the pintle 13 is bent over the edge of one of the hinge jaws. This is necessary for inserting and removing the pintle. The other end 14 of the pintle terminates at the middle point or approximately the middle point of the bearing- 15 so that there will never be any danger of the end of the pintle mutilating the inner tube or the patch. For this reason the bearings 15 are made much longer than the bearings 10 andll. The strips 8 and 94 are made shorter than the tube 1 so that thel strips are spaced from the ends of the tube. This will provide a flexibility in the ends of the patch. This will prevent chang of the inner tube about the Aends of the patch. The strips 8 and 9 5 are preferably made of flexible leather, but it is apparent that other flexible tough material may be used for this purpose. The hinging of the straps 8 and 9 together renders the patch exlble at all pointsffso that the flexibility of tleinner tube is 'notimp'eded by the pate What I claim, is,-

l. A tire patch and guard for the ilmer tube of a pneumatic tire consisting of a sheet of elastic material formed into a tube with the edges of the sheet lapping past each other anda exible hinge therefor consisting of strips of flexible material attached tosaid' patch near theY lapped edges thereof and having interlocking'bearings on their meeting edgesand a pintle running through all of said bearings except one and termig manana nating near the longitudinal center of the last bearing, whereby said last bearing forms a guard to prevent the mutilation of the inner tube by the end of the pintle.

2. A tire patch for the inner tubeof a pneumatic tire consisting of a sheet of ilexible material formed into a tubular member with the edges thereof lapped past each other and the inner edge terminating with a feather edge and a flexible hinge connection. for said tubular member to secure the same on the inner tube consisting of soft tough leather strips doubled to form bearings kand the free edges attached to said tubular member near the lapped edges thereof and the meeting edges of said folded Y strips being cut away to form interlocking bearings, and a pintle running through all said bearings except the last and said pin- 2@ tle terminating at the middle point of the last bearing.

VY3. A. tire patch Yfor the inner tlibe of a pneumatic tire consisting of a sheet of dexible material formed into a tubular member with the edges thereof lapped past each other and the inner edge terminating With a feather edge and a flexible hinge connection for said tubular member consisting of soft tough leather strips attached to said tubular member neark the lapped edges thereof and spaced fromthe ends of the tubular member to permit easy coperation of the tubular member with the inner tube and having interlocking bearings, and a pintle running through said bearings.

ln testimony whereof, ll set my hand in the presence of two witnesses, this 23rd day of July, 1914:.
